Troubleshooting DNS Issues: 8 Steps to Get Your Internet Back On Track

To troubleshoot your DNS issues, let’s go through a series of steps:

Check for malware: Since some of the behavior you described is indicative of malware that hijacks DNS, it’s essential to run a full system scan using an anti-malware software.
Update your operating system and software: Ensure that all your operating system, browser, and other software are up-to-date with the latest security patches.
Check for conflicting network settings: Make sure that you don’t have any conflicting network settings or profiles that could be affecting your DNS resolution. Check your Network & Internet settings to ensure that you’re not using a VPN or proxy server that’s interfering with your DNS.
Use a different DNS service: Try switching to a different DNS service, such as Google Public DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1), to see if that resolves your issues.
Reset browser settings: If you’re using a web browser, try resetting its settings to their default values to see if that resolves any DNS-related issues.
Check for DNS cache poisoning: Run a tool like dig or nslookup with the -n option to check for DNS cache poisoning, which can cause your DNS resolution to be incorrect.
Run a network scan: Use a tool like netstat or ss (on Linux/macOS) or the built-in Windows utility Network and Sharing Center to scan your network and identify any issues with your DNS resolution.
Check your router’s settings: If you’re using a router, check its settings to ensure that it’s not interfering with your DNS resolution.

By following these steps, you should be able to identify the root cause of your DNS issues and make the necessary adjustments to resolve them.

Additionally, if you have speedtest installed, running speedtest::spd_test() will give you information about your internet connection’s speed and latency. This can help you determine if there are any issues with your internet connection that might be affecting your DNS resolution.
